I might reframe the discussion slightly. Wikipedia is growing with respect to time (that would seem factually-verifiable if the number of topics with a Wiki page is larger in each successive year). Increasing the number of pages should increase the number of pages that are controversial, problematic, or "echo-chambers" in absolute terms. Are they increasing as a proportion? Is this diminishing the utility of the site in aggregate?
